Subject: [PATCH] fix(build): disable minify to prevent JSC readonly property
 errors

Bun --compile --minify causes JSC to freeze mutable fold accumulator objects between iterations, producing "Attempted to assign to readonly property" on Linux x64. Effect maintainer @mikearnaldi confirms this is a Bun minifier bug (Effect-TS/effect-smol#2126). Disabling minify until Bun resolves the underlying JSC object shape optimization issue. Related: #25873, oven-sh/bun#13394, oven-sh/bun#12655.
